House Martins - Hand Reared (Please put my mind at rest!)

So this evening we let two fledglings go, after looking after them for ten days. We found them last Tuesday on the ground, a nest had been destroyed and they didn’t look good at all. We brought them in and under instructions from my mother in law (who has a wildlife sanctuary) we nursed them back to health. They’ve recently been eating live mealworms mainly, and all I can think about tonight is will they be feeding okay up there?  
I’m also hoping they found each other, because one flew off a good few minutes before the other one did.

I appreciate I’m probably being a bit soppy and silly, but I’ve grown quite attached to the little ones! Frowning2 Just hope they’ll be okay out there. Fingers crossed tone2
